I am sure that everyone is familiar with some of the problems with VATS. I am experiancing the typical VATS problem, sometimes my car won't start (even after replacing the key).

I went in to my Tuner CATS program and unchecked the VATS and VATS diagnostic. Then I burned a new EPROM. The problem still occors. Its actually like I didn't change anything at all.

The definition file I am working with is the $8d.

Has anyone had this problem, and what can I do to fix it?

Thanks.
